The ADM3251E is a transceiver which has a high speed, 2.5 kV fully isolated, single channel RS-232/V.28. This device is operates from a single 5 V power supply. The device is ideally suited for operation in electrically harsh environments or where RS-232 cables are frequently being plugged and unplugged due to the high ESD protection on the RIN and TOUT […]

The MAX6499 comprises undervoltage and overvoltage comparators for window detection. WHen the monitored voltage is within selected “window”, GATE is enhances and the n-channel MOSFET is on. GATE falls to OUTFB when the monitored voltage falls below the lower limit (V triplow) or exceeds the upper limit (Vtriphigh) of the window, turning off the MOSFET. The MAX6499 enabling the DC-DC […]

To protect downstream circuits from overvoltage conditions that show up during load-dump events or transients, we can use the MAX6495–MAX6499/MAX6397/MAX6398 overvoltage protection (OVP) devices. Here’s the circuit diagram: This devices work by controlling an n-channel MOSFET wired in series with the power rail. The gate pulls low and the MOSFET shuts off, disconnecting the power rail when the voltage surpasses […]
